Down the road I will get big bulbs for flowering. Is metal halide better than High pressure sodium bulbs? I need low heat if possible. I think MH doesn't get as hot as HPS. I think. Mr. Green on Youtube says he uses 400 watt Metal Halide for flowering and flouros for vegging. Right now I just have the Compact Flourescents, daylight and warm. 4 total bulbs but I only have 3 sockets. I need to wire some kind of device like I have seen, it's CFL lights wired together in series or parallel, I can't tell which wiring diagram to use though. I need help wiring them all to one plug. I'm going to run wire for an electric outlet in my attic, and need help with the series-style wiring of CFL sockets. Has anybody done this or know anything about wiring that could help me out???
